seg: Disomic and polysomic segregation patterns

In segtest: Tests for Segregation Distortion in Polyploids

Disomic and polysomic segregation patterns

Description

Gamete frequencies for all possible disomic and polysomic segregation patterns for even ploidies 2 through 20. If you need higher ploidy levels, let me know and I'll update it (it's very easy).

Usage

seg

Format

A data frame with the following columns

ploidy

The ploidy of the parent.

g

The genotype of the parent.

m

The pairing configuration given disomic inheritance. See Gerard et al (2018).

p

The gamete frequencies. Element p[[i]] is the probability a gamete will have dosage i-1.

mode

Whether the inheritance pattern that leads to these gamete frequencies is "disomic", "polysomic", or "both".
